HDL Modeling of Convective Accelerometers for System Design and Optimization

Abstract : This study concerns the integration of convective accelerometers on CMOS. The design approach is based on an HDL modeling of the sensing cell. The development of a monolithic system is then undertaken, using multi-domain simulations, within the microelectronics design environment. For illustration, the sensor equivalent input noise (i.e. the resolution) is computed for various readout circuitry configurations: a simple instrumentation amplifier, a customized low-noise amplifier and a chopper-stabilized amplifier with a track-and-hold signal demodulator. Finally, a noise equivalent acceleration below 1 mg/√Hz has been reached, which is interesting for applications in consumer electronics.
